Pyrrole-imidazole polyamide (PIP) can specifically bind in the B-DNA minor groove that has been used in several biological applications, such as anti-cancer activity, gene expression and translation control, and visualization of complex genomic areas. c-kit is a family member of the Tyrosine Kinase (RTK) type III receptor and plays a vital role in tumor growth, proliferation, differentiation, and cell apoptosis; however, its mutations and overexpression induce tumor dysfunction. Here, we designed and synthesized five matched PIPs that can recognize and bind to the DNA sequence in the oncogene c-kit promoter region, and evaluated their anti-cancer activity. The RTCA assay findings revealed that the PIPs would prevent the proliferation of cancer cells A549 and SGC-7901. EMSA assay showed that the PIPs were actively interacting with the c-kit gene target DNA. RT-PCR and Western blot assays have an effect on expression levels of the c-kit gene in the presence of PIPs. Flow cytometry and wound-healing assays showed that PIPs 4, 5 would cause apoptosis of cancer cells and inhibit the migration of cells, respectively. Overall findings indicate that PIP 5 has a relatively significant intracellular and extracellular impact on the target, contributing to migration and proliferation reduction, and cancer cell apoptosis. In addition, PIP has a certain ability to evolve into c-kit gene-targeting drugs.With an estimated worldwide production of 190 billion kg per year, and due to its high organic load, cheese whey represents a huge opportunity for bioenergy and biochemicals production. Several physical, chemical and biological processes have been proposed to valorise cheese whey by producing biofuels (methane, hydrogen, and ethanol), electric energy, and/or chemical commodities (carboxylic acids, proteins, and biopolymers). A biorefinery concept, in which several value-added products are obtained from cheese whey through a cascade of biotechnological processes, is an opportunity for increasing the product spectrum of dairy industries while allowing for sustainable management of the residual streams and reducing disposal costs for the final residues. https://www.selleckchem.com/products/abraxane-nab-paclitaxel.html This review critically analyses the different treatment options available for energy and materials recovery from cheese whey, their combinations and perspectives for implementation. Thus, instead of focusing on a specific valorisation platform, in the present review the most relevant aspects of each strategy are analysed to support the integration of different routes, in order to identify the most appropriate treatment train.Shallow erosion is caused by processes such as landsliding, snow gliding, avalanches, animal trampling, or human activities and frequently occurs on high mountain grasslands. It can lead to significant long-term losses of grassland and related ecosystem services, e.g. fodder production, or water retention. Since restoration of subalpine and alpine ecosystems is difficult, prevention of shallow erosion is of vital importance for damage control. However, current knowledge on relationships between grassland ecology, management and shallow erosion resistance is very limited. In this study, we assessed relationships between the surface-mat stability of the topsoil (0-10 cm depth), vegetation cover, species diversity, growth patterns, indicator plant species for high and low tensile strength, soil texture, total nitrogen, and soil organic carbon. Vegetation composition significantly influenced the surface-mat stability of subalpine grasslands. Some key species were associated with higher reinforcement than other species. However, surface-mat stability neither depended on the vegetation type (grass or forb), nor on the root type, but rather on individual species characteristics such as roots and clonal structures as well as a certain plant and structural diversity. A balanced nutrient supply was associated with higher surface-mat stability, while soil texture had no effect. We hypothesized that stabilizing effects of plant-plant connections in tightly interwoven, dense root and clonal structure systems dominate over effects of root-soil connections. Thus, effects of soil texture may be negligible for the surface-mat stability. In general, our results show that adapted grassland management can be used as preventive erosion control measure on subalpine grasslands.While creosote components have very low water solubility, concerns have been raised about potential environmental effects and stimulated research to minimize migration. Best management practices have been developed but there are few data quantifying their effects. The effects of post-treatment steaming on migration of polycyclic aromatic hydrocarbons (PAHs) from horizontally oriented creosote treated southern pine decking subjected to simulated rainfall were examined. Twelve of the 16 PAHs examined were detected in runoff during the rainfall exposure but at concentrations well below those predicted by water solubility. PAH levels declined with increasing rainfall time, although the differences were sometimes slight. Steaming for 1 h had minimal effect on PAH levels in runoff while 3 h of steaming produced more noticeable reductions ranging from ~20 to 80% for naphthalene, acenaphthylene, and acenaphthene. Longer post-treatment steaming times reduced initial losses of creosote components from treated wood.Triclocarban (TCC), a typical emerging contaminant, was abundantly released into environment and frequently detected in practical wastewater treatment plants. However it is also an important material when being added to personal skin care products as a antibacterial agent. In this work, the behavior of TCC in wastewater treatment process was investigated. Experiments showed that ~82% of influent TCC was removed by activated sludge adsorption and its adsorption isotherm was well fitted with Linear model and Freundich model. High levels of TCC had seriously impact on the settleability, dewaterability and extracellular polymetric substance (EPS) of activated sludge, even on effluent turbidity after a long-term exposure. Furthermore, the performance of biological wastewater treatment was damaged by TCC long-term exposure as well. The removal rates of total nitrogen and phosphorus decreased from 91.2 ± 2.1% to 72.6 ± 2.2% and from 94.7 ± 3.1% to 78.4 ± 2.3%, respectively, with TCC level increasing from 0 to 100 μg/L.
